ROBERT W. MUIR. or HUNTER, NORTH DAKOTA.

ACCELERATOR FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed December 26,1918. Serial No. 268,228.

To all avhom it may concern:

Be 1t known that I, ROBERT V. More, a citizen of the United States, residing at Hunter, in the county of Cass and State of North Dakota, have invented certain new and useful Improvements in Accelerators for Automobiles, of which the following is a specification.

My invention relates to accelerators for automobiles and the object is to provide a foot operated device which is adapted for operation in such manner that the customary strain on the foot and legof the operator is eliminated. A further object is to provide adevice which will addtothe safety of the occupants of the automobile by rendering accidental acceleration unlikely when the automobile is moving over rough roads. A further object is to provide a device by means of which the operator may accelerate the car to ordinary speed without likelihood of exceeding this speed unless he so desire.

' The full objects and advantages of my invention will appear in connection with the detailed description thereof and the novel features embodied in my inventive 1dea are particularly pointed out in the claims.

Referring to the accompanying drawings which illustrate the application of my 111- vention in one form, V

Figure 1 1s atop plan view of the front ing my attachment in position.

In the drawings the character 10 designates the side members of the chassis, 12 the engine or motor, 14 the radiator, 16 the dashboard, 18 the foot-board, 20 the stationary steering post for steering column 22"at the side of which extends the customary throttle shaft 24 having a crank arm 26. The carbureter 28is provided with a throttle lever 30 for controlling the customary'butterfly valve. An accelerator rod 32 extends through the dash-board and is provided at itsrear end with an angular portion 345 in proximity to the foot boards and this rodex tends forwardly and to its other end is secured an offset member or ring 36. To one side of the ofiset member a flexible member 38 is attached and to-the other side of the offset member is attached afle-xible connec tion 40 extending tothe throttle 'lever'30.

A spring 42 normally holds the throttle lever in position to close the butterfly valve and cut oil" gas to the engine. The flexible conany point'where the hand device is set.

nection 38 extends from the offset member to the crank arm 26. The accelerator rod extendsthrough a sleeve 4a screw threaded into the foot board so that the sleeve may have its position adjusted for a purpose portion 34 of the accelerator rod extends in a downward direction. In order to accelerate the car the foot may be placed flat upon the foot-board at either the right or the left side of the member 34 and by sliding the foot against this member the rod 32 is turned andthe position of the offset member is shifted. The flexible connection L0 will be pulled regardless of the direction in which the rod 32 is turned and the throttle will thereby be opened by an amount proportionate to the sliding move ment of the foot. If the foot is placed at the outer end of the member 34: and moved side-wise it accelerates the car a certain amount, but'if the foot is placed closer to the rod 32, then the same relative movement of the foot will accelerate the car a greater amount. In order to accelerate the car to ordinary speed the operator may place his foot back of the member 34: and push in a forportion of an automobile; Fig. 2is a vertical sectionthrough the dash board showwardly direction so as to move the rod 32 lengthwise. The screw threaded sleeve 4E4: may be adjusted to such position that the desired acceleration will be obtained when the member 34 comes into engagement with the rear end of the sleeve. In the use of my device the operator rests the foot firmly upon the foot board adjacent either side of the member 34: or upon the rear of this member. It is not necessary to hold the foot in a cramped position and the accelerator may be held firmly in any desired position regardless of the roughness of the road which is traveled over. This eliminates jerky motion of the car and reduces the strain on the same and also reduces wearing of the tires. 7 p

My accelerator may be used in connection with the customary hand throttle operating device, and will take up the acceleration at In some automobiles the foot board is set at such an angle that it is desirable to secure a block 46 to the foot board at the place where the rod 32 passes therethrough. It

i also desirable that a spring 48 be placed between the block 48 or the foot board and the angle member 34 to normally hold the rod 32 in retracted position.

I claim:

1. An accelerator for automobiles comprising a rod extending through the foot board, a foot member secured at an angle to the end of said rod whereby the latter may be turned in either direction as desired by the foot of the operator, and connec tions between the other end of said rod and the throttle for opening the latter by rotative movement of said rod in either direction.

2. An accelerator for automobiles comprising a rod extending through the footboard, a foot member secured at an angle to the end of said rod whereby the latter may be turned in either direction as desired by the foot of the operator, an oflset member secured to the other end of said rod, and connections between said member and the throttle for opening the latter by rotative movement of said rod in either direction.

3. An accelerator for automobiles comprising a rod extending through the footboard, a foot member secured at an angle to the end of said rod whereby the latter may be turned in either direction as desired, a ring secured to the other end of said rod and a flexible connection between said ring and the throttle lever.

at. A11 accelerator for automobiles comprising a rod extending through the foot board, a foot member secured to the end of said rod, an adjustable engaging member upported on said foot-board with which said foot member is adapted to engage when said rod is pushed longitudinally, and coni nections between the other end of said rod and the throttle.

5. An accelerator for automobiles comprising a rod extending through the foot board, a foot member secured to the end of said rod, an engaging member supported for nally, and connections between said rod and the throttle. v

7. An accelerator for automobiles comprising a rod extending through the foot board, a foot member secured at an angle to the end of said rod whereby the latter may be turned in either direction as desired, an adjustable engaging member supported on said foot board with which said foot member is adapted to engage when said rod is pushed longitudinally, and connections between the other end of said rod and the throttle adapted to open the latter when the rod is turned in either direction or is pushed longitudinally.

In testimony whereof I hereunto afiix my signature.
